The original 1980s voice cast of the Teenage Mutant Ninja Turtles cartoons will reunite for a teenage mutant hourlong special.

Cam Clarke, Rob Paulsen, Barry Gordon, and Townsend Coleman will reprise their original pizza-slinging roles as Leonardo, Raphael, Donatello, and Michelangelo on the new iteration of the series. They’ll appear in Friday’s episode “Wormquake!,” which airs at 7 p.m. on Nickelodeon.

The reunion isn’t the buzziest thing this year when it comes to the heroes in a half-shell. The boys in purple, red, orange, and blue will enjoy their 30th birthday this May (the original comic book appeared in 1984) and as such, the series’ creators Kevin Eastman and Peter Laird will release a commemorative issue to celebrate the anniversary.
